Species List

Fallfish, Semotilus corporalis

 

                   DISTRIBUTION:

FALL FISH

 

                   DESCRIPTION:   The fallfish has a similar body shape as the creek chub, but is more

                                    laterally compressed and has a more pointed head.  Its back is dark olive, brown

                                    to black in colour and its sides are silvery to a white belly.  The scales are large

                                    with 43 – 50 along the lateral line.  Young fallfish generally have distinct mid-lateral

                                    band.  They also have a dark pigmentation (cresent shaped) on the anterior edge

                                    of its scales. The average length is around 5 inches, but the fallfish can grow

                                    between 10 and 15 inches.

 

                          BIOLOGY:  The fallfish are commonly found in pools and runs of rivers, but are

                                    also found in lakes.  Food consist mostly of aquatic insects, plankton, and other

                                    fishes.  The fallfish spawn in the spring.  Like creek chub males the male fallfish takes

                                    on a rosy colouration and develops tubercles on its head. The male creates a

                                    depression for egg deposition by removing pebbles with its mouth.  The fertilized, non-

                                    adhesive eggs are then covered with gravel.  Commonly referred to as “chub” by anglers, fallfish

                                    are rarely kept for food.   They are preyed upon by fish-eating birds and larger fish.
